LZ1535 Erbium Glass Laser Transmitter
LZ1535-1KHz-5ns-40uJ-25mm
40 uJ at 1 kHz, 5 ns
High repetition-rate transmitter for scanning LiDAR and compact rangefinders. Passively Q-switched erbium glass gives a pulse with no tail, and the 1535 nm wavelength sits in the eye-safe band, so it can be used at far higher energy than a 905 nm source in the same application.
